SPECIFICATION forming part of Letters Patent No. 301,018, dated June 24,1884, Application filed January 21, 1884. (No model.)

To all whom, t may concern:

Be it known that I, FREDERICK F. STREET, of Hartford, in the county ofHartford and State of Connecticut, have invented a new and usefulImprovement in Dry Closets, of which the following description andclaims constitute the specification, Iand which is illustrated by theaccompanying drawing.

The figure shown is a side view of an apparatus embodying myimprovement.

This invention is particularly adapted to the closets of railroad-cars.Its function is to close the lower end of the discharge-chamber of sucha closet whenever the upper end is covered by a user, and thus toprevent access of cold air to the person of the occupant.

A in the drawing is a discharge-chamber of ordinary construction, exceptthat its lower end, instead of being cut off at right angles with theaxis of the chamber, is cut off diagonally, as shown in the drawing.

B is an elliptic disk large enough to close the lower end of thedischarge-chamber when shut against the latter.

C is an anvil rigidly attached to or forming a part of the disk.

I) is, a leverof the rst order, the weight end of which is rigidlyfastened to the disk B, and the fulcrum of which is pivoted to an armattached to the discharge-chamber.

E is a connecting-rod, the lower part of which is encircled by thespiral spring F.

The spring is held against upward movement by the nut G, working on ascrew-thread on the rod E, and it is supported from below by thejournaled and perforated rest II. The journals of that rest turn injournal-boxes in the forked power end of the lever D. The lower end ofthe rod E passes through the perforation in the rest I-I, and below therest the rod is furnished with the nut I. The upper end of the rod ispivoted to the arm K by a pivot, J, which passes through the forkedlower end of that arm, and which works in a slot inthe upper end of therod E. The arm K is rigidly attached at its upper end to the seat-lid L.

The mode of operation of this apparatus is as follows: When the closetis not being used,

the parts are in the positions shown in the 5c dotted lines. IVhen theuser raises the seatlid, the arm K forces down the rod E, and that rod,through the nut G, the spring F, and the rest I-I, forcesdown the powerend of the lever D, and forces up the disk B, so that the 5f latter willclose the lower end of the dischargechamber. Thereupon any excrementwhich falls through the discharge-chamber, when it strikes the uppersurface of the disk B, will tend to slide down that surface till itreaches 6 the part directly over the anvil C. `Vihen the user rises fromthe seat, he closes the seat-lid. The slot in the upper end of the rod Eallows the lid to be nearly closed down upon the seat before the disk Bis removed from the lower 6I end of the discharge-chamber, and in sodoing enables the lid to arrest the upward motion of any paper thatotherwise might be blown backward and into the room occupied by thecloset. Vhen the seat-lid is entirely closed 7 down, the disk B willagain be in the position shown in the dottedlines. Then, if anyexcrement adheres, by freezing or otherwise, to the upper surface of thedisk B, it may be dislodged by a blow of a hammer upon the anvil 7 C.The connection between the rod E and the lever D is an elastic, and notsimply a pivotal, one, to the end that any matter frozen or otherwiseadhering to the upper surface of the disk B will not prevent thecomplete rais- 81 ing of the seat-lid.

I claim as my inventionl. The combination of the discharge-chamber A,the disk B, the lever D, the rest II, the spring F, the rod E, furnishedwith the nuts 8 G and I, and the seat-lid L, furnished with the arm K,all combined and operating t0- gether substantially as described.

2. The combination of the rod E, the nuts G and I, the spring F, therest H, and the le- 9 ver D, and means for operating the same,substantially as described.
